“Windows Phone 7 is the most thoroughly tested mobile platform Microsoft has ever released. We had nearly ten thousand devices running automated tests daily, over a half million hours of active self-hosting use, over three and a half million hours of stress test passes, and eight and a half million hours of fully automated test passes. We’ve had thousands of independent software vendors and early adopters testing our software and giving us great feedback. We’re ready,” said Terry Myerson.
